More than 1,500 business leaders and 40 heads of state or government will attend the Jan. 21-24 meeting of the World Economic Forum to network and discuss big themes -- everything from the price of oil to the future of the Internet. This year they are meeting in the midst of upheaval, with security forces on heightened alert after attacks in Paris, the European Central Bank considering a radical government bond-buying program and the safe-haven Swiss franc rocketing.
